Answer:

We use the quotient.....#"Mass"/"Molar mass"="Number of moles..."#

Explanation:

And so for #"water"# we gots....

#(130*kgxx10^3*g*kg^-1)/(18.011*g*mol^-1)=7218.2*mol#

And for #"nitrous oxide"# we gots....

#(4.6*g)/(44.01*g*mol^-1)=??*mol#

And for #"sulfur dioxide"# we gots....

#1.82*molxx64.07*g*mol^-1=??*g#

And for #"methylene chloride"# we gots....

#0.0484*molxx84.93*g*mol^-1=??*g#

Do you see what I have done with the quotient?
